应用CT三维重建对八髎穴取穴方法研究

Study on the location of Baliao acupoint by using CT 3D reconstruction: Individual bone marker equation method

目的:通过测量横距、纵距与髂距、骶距和髂骶距,计算相应的回归方程,总结出临床实用的取穴方法,即"个体化骨性标志方程法"。方法:对290例行盆腔CT检查(包含盆腔)患者资料进行三维重建,分别测量髂距、骶距、髂骶距、横距、纵距,并对横距、纵距与髂距、骶距和髂骶距分别进行直线相关与回归分析。结果:男性髂骶距>女性,髂距、髂距/髂骶距比值<女性;男女横距无统计学差异,上-次髎纵距有统计学差异(P<0.05);上髎横距、次髎横距与髂距呈直线相关关系,回归方程分别为y=2.384+0.182x,y=2.198+0.136x,下髎横距与髂骶距呈直线相关关系,回归方程为y=2.239+0.068x,所有平均纵距与髂骶距呈直线相关关系,回归方程分别为y=0.373+0.105x,y=0.765+0.067x,y=0.796+0.042x;髂后上棘连线多位于上髎水平线上(男性73.13%,女性60.78%),或位于上-次髎水平线上(男性10.45%,女性29.41%),极少数位于次髎水平线上(男性1.49%,女性5.88%),髂骶距中点多位于中髎水平线上(男性67.16%,女性90.20%),或位于次-中髎水平线(男性31.34%,女性5.88%),极少数位于中-下髎水平线(男性1.49%,女性3.92%)。结论:"个体化骨性标志方程法"既能起到类似骨度分寸的个体化作用,又能在大数据的支撑下通过方程计算,达到精准取穴的目的。

Objective： To calculate the corresponding regression equation by measuring the transverse and longitudinal distance, the distance of the iliac and the sacral, the iliac and sacral distance, and summarize the clinical practice of location of acupoint ＂individual bone marker equation method＂. Methods： 290 cases with pelvic CT examination（including pelvic） patients were collected for 3D reconstruction including iliac distance, sacral distance, iliac and sacral distance, transverse and longitudinal distance, the linear correlation and regression analysis were used to analyze the transverse and longitudinal distance, the distance of the iliac and the sacral, the iliac and sacral distance respectively. Results： Male was more than female in the iliac and sacral distance, and the iliac, sacral/iliac and sacral ratio were less than female; male and female had no significant difference on the transverse distance, vertical distance of Shangliao（BL31） and Ciliao（BL32） had significant difference; transverse distance of Shangliao（BL31） and Ciliao（BL32）, with iliac showed a linear correlation, regression equations were y=2.384＋0.182 x, y=2.198＋0.136 x, transverse distance of Xialiao（BL34） and iliac and sacral distance showed a linear correlation, the regression equation was y=2.239＋0.068 x, the average longitudinal distance and all iliac and sacral distance showed a linear correlation, and regression equations were y=0.373＋0.105 x, y=0.765＋0.067 x, y=0.796＋0.042x; posterior superior iliac spine line was located at Shangliao（BL31） horizontal line（73.13% male, 60.78% female）, or at Shangliao（BL31） and Ciliao（BL32） horizontal line（10.45% male, 29.41% female）, very few was located at Ciliao（BL32） horizontal line（1.49% male, 5.88% female）, midpoint of the iliacand sacral was located at Zhongliao（BL33） horizontal line（67.16% male, 90.20%female）, or at Ciliao（BL32） and Zhongliao（BL33） horizontal line（31.34% male, female 5.88%）, very few was located at Zhongliao（BL33） and Xialiao（BL34） horizontal line（1.49% male, 3.92% female）. Conclusion： ‘Individual bone marker equation method＇ is similar to that of bone measured individual role, and could also calculate through equation supported by large data, so as to achieve the purpose of accurate location of acupoints.
